I mentioned quite some time ago that for if you are using Lycosa and you use W, A, S, D for movement you will not be able to move diagonally because when you hold down W the keyboard will not detect the key press on A, combination of W and D is working fine. This is especially bad if you are playing FPS a lot and likes to run circle around your enemy. I remembered there are few more issues I spotted with the keyboard but can't remember.

I'm not sure whether they fix it on the newer version of Lycosa or not.

Ah, the random key dying on you problem.

It's a problem with the keyboard as well but it happens very rarely in my case so it's not a big problem to me, but when it happens, it can make you scream out of frustration especially when you are in the middle of a big fight.

The W+A problem is guaranteed to happen 100% every time you hold down W and press A.
